Sergey Sirotkin says he feels 'ready' for Formula 1 after his practice outing for Sauber at the Russian Grand Prix.
Sirotkin took part in the opening session in place of Esteban Gutierrez and set the 17th quickest time.
Formula Renault 3.5 race winner Sirotkin, who was originally set for a Formula 1 seat this year, says he feels ready to make the step up to the top echelon of the sport.
"I felt it after Bahrain a little, but it wasn't a proper run," he said, referring to his outing in the post-race test earlier in the season. "Here [it] is a chance to compare and it was a surprise to me that it was a bit easier than I thought.
"I feel myself more than ready for this step - I just need the chance. Motorsport in Russia is progressing quite well. This weekend made a big step forward and it helps to attract the people and make them interested.
"We're working to get the seat next year. There's nothing I can say now officially, but we are working. As soon as we make any decision we can think about some extra testing options maybe to be ready earlier."
